I know the answer, at least I think I do as I am now questioning myself! It's just I've seen a few jobs recently where the electrician (or who ever did the job) did not give any fault protection to the armoured cable, so I am wondering if I am missing something?
The most recent example from...
Hi
I have only had a quick look at a fault so haven’t gone too far into it.
Lighting mcb tripped out, elderly lady wanted it checked out before it went back on so meggered it, all lights worked but rcd would not trip.
It’s a BG 3+3 split load installed by someone when the heating was done about...
Sorry this is a bit of a long read but I’d be extremely grateful if someone can help me understand RCDs and testing methods of them.
I know RCD test applies a fault current but in what way? I understand how continuity/IR and the other test work so it helps me know what to do, what’s going on...
Hi All,
Looking for some advice into my build.
What I've basically done is add additional RCD protection to my 100% off-grid 12V 3300W Inverter system by adding RCBO breakers to both AC outputs of the inverter (12V Giandel 3300W 240V).
Things you should know for context:
Inverter has no N-G...
The meter box RCD for my power outlets in my home trips at random times, approximately every 13 hours. Have used a portable RCD box to test every appliance plugged into outlets but the portable RCD doesn’t trip. Any ideas? Faulty outlet? Faulty RCD ( it’s 25-30 years old)?
No other circuit...
I have a dual board consumer unit. Both sides have a RCD. The left hand side of the board has all the MCBs for all the 6 ring mains for the property. The right side of the board has the lighting and hob and cooker for the house.
Whenever a current is drawn from a socket the right side RCD...
Hi All,
I am new here.
I searched the forum regarding this issue and most professional advice was that the heating element should be at fault.
I am a DIY person and I would not have a problem replacing it myself, only that a new heating element costs £45 on Zanussi.co.uk and I would not want...
Hi.
Wondering if anyone had any idea what might be happening. Last night I damaged a pendant light fitting by accident, not enough to stop it working.
However later in the evening when my car charger started at 11:30PM the whole house RCD tripped.
I only thought back to the light accident as...
Hi, I have an underfloor heating system in a room (just less than 2kW). It works absolutely beautifully but an electrician who came to swap a socket in that room said that it looked like a ‘lazy install’. He was unprofessional and a rip-off - so I want to get someone else to check it - but I...
6 year old Neff combi Oven/Microwave trips the Schneider 30mA EZ9R33263 RCD on our distribution board when we try to use the convection oven but runs the microwave fine, even on MAX setting.
One of us (not me) slightly nuked one of those part-baked baguettes using the microwave but hardly any...
Hello,
I'm not an electrician. My RCD at home constantly trips. I tried turning off the power, resetting the RCD and putting the circuits back one by one, to work out what was tripping it. All were okay, except when I turned back on 'downstairs sockets' or 'upstairs sockets' either one of those...
Hello
Elderly woman here, read lots of forums like this looking for advice but currently none the wiser,!
I had Led PIR lights installed recently, replacing old pir security lights and an old decorative light at the front door all using the original wiring. An electrician did the work. The...
Scame Advance 2 RCD interlock socket, has anyone fitted these? There is no access to the RCD when energised. How can you conduct an RCD function test?
I’ve attached the data sheet with a product photo
I just want to check how I should be interpreting section 705.
705.411.1 states required disconnection devices, the first two indents covering final circuits and sockets, requiring 30ma and 100ma RCD's depending on rating of socket.
Indent 3 says " all other circuits" need 300ma RCD.
Does that...
Hi guys, starting a new install on a job soon and having a complete mind blank. The supply at the main cut-out is a 3 phase TNCS supply. There is then a 50mm SWA running a considerable distance to a workshop where i will be installing a new TPN board as well as an earth rod to make all the...
Hello guys and girls , I have a question if I may.
Have to go and look at a intermittent fault on rcd , I'm told the circuit holds whilst using light appliances ( TV, etc ) but randomly trips the rcd on heavier loads ( hair dryer ) .
The manual operation of the test button also doesn't work...
Hello all. Can anyone inform me on what the latest guidance on the frequency of RCD testing is? I test my RCD's annually and record the x1/2, x1 and x5 trip and 0-180degrees annually, and replace failures. I also carry out a functional test whilst I'm doing this, and then a further functional...
Hi All,
I'm looking to pick the brains of experienced engineers who have dealt with TT more than I have please.
We have an installation on a site which may or may not be unique. There are four 12m x 12m units inline with each other, all connected as one building, with the plan to build a...
